Sorry to start a new thread but I urgently need to disconect the alarm on my 4200 due to my new key not being synced to the alarm ecu the alarm constantly off whenever I drive! Cheers to anyone that can help
Not being easy to disconnect / bypass is somewhat a requirement of alarm's sadly
The siren is in the boot, left hand side, behind the liner. That's quite easy to disconnect, but it may well continue to wail for a while depending on the state of its internal battery.
No idea how you're going to be able to stop the flashers.
I *suspect* your best bet will be a new set of plibs and ECU from a break (David Askew, for example) but would love to hear that I'm wrong.
